1a. What is the estimate of the common population proportion? 1b. The computed z-test statistic value for this scenario is -1.83. What is the corresponding p-value for the observed test statistic? 1c. True or False: The p-value provides the probability that the rate of completing a task is lower for tab collectors than streamlined searchers 1d. Based on the p-value, the researcher fails to reject the null hypothesis. Which of the following is NOT possible about these results? a. Result is correct b. Result is incorrect -- a Type I error was made c. Result is incorrect -- a Type II error was made
